Hardly anybody wants to self custody. It's the literal reason banks got started. If blockchain can't even solve the most basic use case of the financial system, it's not going to replace it.
I'm not claiming banks don't serve a good purpose.
I'm not claiming anyone should hold all their net worth on a blockchain.
But blockchains do have extremely desirable properties in preventing fraud _on the chain_.
I would love to have mathematical proof that my government is not fraudulently misusing my tax dollars, at least at some level. Who wouldn't?
I would love to hold some portion of my assets in a way that no one, even the government, can seize it or freeze it. What if my government is Cyprus in 2013? What if my government is the 1940s Nazi government? I want to be able to flee the country without losing my livelihood to tyranny and abuse.
I don't buy this 'bitcoin saves you from tyranny' argument. Tyrannical governments are able to threaten your physical security. All the tokens in the world are no good if they've imprisoned you. As this Sam character has just learned, the hard way.
